The Coherent 7970 YAG Laser represents Coherent’s commitment to the state of the art in Nd: YAG laser technology for ophthalmology. The optics on the Coherent 7970 YAG Laser offset the treatment beam relative to the HeNe aiming beam to compensate for the astigmatic effect of the patient’s cornea, maximizing laser performance in a 5-mm diameter. The 16 degree cone angle of the Nd: YAG treatment beam assures optical breakdown at the posterior capsule, thus minimizing damage to the IOL or the retina. To achieve optimal intensity, the spot size of less than 7 microns in diameter featured on the Coherent 7970 YAG Laser provides optimum energy concentration.
